3.6 Power Routing in the Display
Following is a basic overview of power routing. This may vary depending on the
pixel dimensions and LED color of each display. Check for exact power routing on
the Shop Drawing for the specific display.
A general power routing, shown in Figure 11, is summarized as follows. The
numbers in this list correspond with the numbers in the diagram.
1. Power terminates to the J-box on the back of the display.
2. Power continues through pre-terminated wires to the power termination
panel, which include the transformer and filter.
3. Power passes through the transformer where 120VAC voltage is stepped
down to 10VAC for use by the controller.
4. Power is routed to the power supplies which provide DC voltage to the
modules. Power supplies provide 9 VDC power to the amber modules and
6.5 VDC to the red modules.
5. Power is also sent to the fans and to the thermostat, if installed.
Note: Power supplies are preset to proper voltage levels. Contact Daktronics
Customer Service for proper settings.
